150 Remarks on the Flora Scotica of Dr Hooker. 
of species. In this respect, very fe\r individuals indeed can 
judge with accuracy ; and, probably in this particular case, 
none who have not subjected themselves to the same labour, 
and enjoyed the same advantages as our author. But that 
there are deficiencies, could easily be shewn. The following 
may serve as a specimen : Sonclmb ’palustr'is^ — on Don Braes, 
near Aberdeen ; Ywia hithynica^ — not uncommon about Aber- 
deen ; Epilohium roseum^ — in the outer Hebrides. 
The common Grey Oat of the North Highlands and He- 
brides has an equal right to be admitted with Avena fatua, or 
Agrostemma GithagOj occurring in corn fields in various parts 
of Scotland. 
The low, robust Alpine Juniper, so common in the Hebrides 
and West Highlands, where the common kind is not seen, is 
worthy of particular notice, if not as a species, at least as a va- 
riety 
A pentandrous Cerastkim, very different from C. semide- 
candrmn^ but growing along with it and C. tetrandrum, in va- 
rious parts of Scotland, along the coast : — 
NupJiar , differing so much from N. lutea^ as to be at 
least a variety, if not a distinct species, and approaching in cha- 
racter to N. minima, but much larger, plentiful in the Corby 
Loch, Aberdeenshire, and not seen elsewhere. 
The redundancy of species is, in the next place, to be pointed 
out, or the admission of plants not truly indigenous. Perhaps, 
in regard to this subject, it would be proper in Floras to divide 
the plants into those indisputably indigenous ; those introduced 
by accident or design, and naturalised ; and those exotics which 
have gained but a very slender footing, not sufficient to admit 
them into the second class. Examples of the second class arc, 
Tanacetum vulgar e, Scandix odorata, Avena fatua, Imperato- 
ria OstrutMum, Chelidonium majiis. Of the third kind, those 
which are most objectionable in the Flora Scotica, appear to be 
the following ; Phalaris canariensls, Medicago falcata, Cocldea-^ 
ria Armoracia, Brassica Rapa, Corniis sanguinea, AntJiemis no- 
hilis, Imda Helenmm, Carum Cariii, Rihes ruhrum, R. nigrum. 
R. Grossnlaria, Vinca minor, Folcmonium carideum, Orniilw- 
galum umhdlaiinn- Asaruin Eirrop^cum.
